To all whom it may concern.

Be it known that I, Fnnnnnro L.- VVANK- LYN, a subject of the KingofGreat Britain,

of-the city of Montreal, Province ofQueoec, Dominion of Canada, haveinvented certain new and useful Improvements in Torpedoes; and I dohereby declare that the following is a ful1,clear, and exact descriptionthereof. 1 c

My invention relates particularly to torpedoes for use on a railway forsignalling an approaching train when the train is out of reach oftelegraphic and telephonic communication, and has particular referenceto the railway track torpedo disclosed in my United Statespatentgranted, October 19th,

1920, under No. 1,355,871 The present invention has for its object tosimplify the manufacture ofthis type of torpedo and re duce to aminimumthe personal danger from flying parts when thetorpedo isexploded; and. its object is furthermore to increase the capacity of thetorpedo to give warning of danger ahead, and further imof the carrierillustrating in dotted lines the prove the device by facilitating theassen1- bling and water-proofing of the parts and rendering the completetorpedo more impervious. The aim of the invention is also to enhance itsresistance to displacement along the rail. p v i I The present inventionconsists in the construction and particular arrangement of partshereinafter specified.

The improveditorpedo consists of a carrier with integral rail-clips ofsteel, brass or other suitable metal, the carrier having secured theretoa contamer for smell pro- ,ducingdetonating and smoke and flashproducing elements, the container being the carrier near its-ends bydiminutive fas-;

tenings.

, After the containeris thus closed the device is treated with awater-proofing composition then sprinkled with sand while wet andfinally dried. ltis preferable to pass the complete torpedo through abath and thenafter sanding it pass it into a steam heated drying chamberafter which it is ready forinspection,and to be packed for shipment tothe consumer. The sanding of the torpedo enhances its resistance todisplacement along the rail. i v v For full comprehension, however, ofmy invention, reference must be had to the ac- ,companyingdrawings inwhich similar reference characters indicate the same'parts, and wherein:

Figure 1 is a perspective view of the underside of torpedo constructedaccording to my invention and villustrating the ends of the containerfolded beneath the carrier and c-rimpedbetween the folded ends thereof;Figure 2 is a transverse sectional view of the torpedo illustrated inFigure l in position upon the rail;

Figure 3 is a plan view of the underside manner of folding the ends;

Figure 4: is a view similar to Figure 1 illustrating a modified form ofcarrier and means securing the ends of the container thereof;

Figure 5 is a view similar to Figure 4: illustrating a furthermodification;

Figureb is a fragmentary side elevation drawn to a preferred scale ofone end of the torpedo illustrating the manner in which the container issecured to the carrier in Figure 1; and

Figures'Y, 8 and 9 are detail fragmentary views illustrating the mannerof folding the container utilized in the construction shown in Figure 1,c

In order to produce my improved, torpedo the carrier 2 and clipsZ-B arestruck from the same piece of metal and the ends of the carrier areformed to afford means for fastening the containerto it by either havingits ends crimped as at 4 and turned "beneath it as shown inFigures 1 and6, or

the ends may be perforated to receive eyelets 5 or other diminutivefastening devlces.

The carrier may also be cut away to reduce the metal required to presenteither of the forms shown in Figures 4 or 5, each form being of thenature of a cross the arms of which in one case (Fig; 1) are widened.

In order tc. provide an effective wateri the combination with acontainer and mean proof non-metallic closure of the ends of thecontainer 6 such ends have their corners folded inwardly shown in.Figure 7 and the end folded back upon. the body as in Eigurc S and givena second fold in ure 9, This container as thus folded has its foldedends fastened to the ends ofthe carrier by the diminutive fasteningdevices 5. The ends of the container need not be folded upon itself whenthe carrier of Figure 1 is employed but may be closed in any suitableway and inserted into the crimps after which the crimpsare compressed,thusv hermetically sealing these ends.

The device completed as shown in Figures 1 and 6 or Figures at, 5, 7, 8and 9 is then treated with a waterproofing composi tion, sprinkled withsand while wet and finally dried. I I V The container illustrated is ofoblong form but may be square, elliptic, circular or any other formrequired without departing from the spirit of my invention.

lVithin the container there is an envelope 12, a tablet 18 and anenvelope 1 the relative dimensions of the envelopes, tablet andcontainer being such that the container is completely filled whencharged. The envelope 12 contains a smoke producing substance which isof a nature to produce a pungent odor on ignition or if desired thissmoke producing substance may be mixed wit another ubstance capable ofproducing a pungent odor. Tablet 13 is composed of an explosive ordetonating and smolre m.- ducing substance and the envelope ll ischarged with a flash producing substance.

An important feature of the invention is the structure which places theexplosive above all metal parts, the beneficial effect being that nopersonal damage can be done, there being no metal parts flung about bythe explosion.-

Furthermore the flash accompanying the detonation will attract theattention of the engine driver even if the vibration of train or thesounding of the whistle should happen to drown the sound of theexplosion and the smoke will have the same effect-if bright sunlightprevails. The pungent odor adds an element of safety.

What I claim is as follows:

1. A railway track torpedo consisting o for fastening the same to a railhead; of a detonator ant. a smoke-producing substance.

A railway track torpedo consisting of the combination with a containerand means for fastening the same to a rail head; of a detonator, asmoke-producing substance and a flash-light powder.

3. A railway track torpedo consisting of the combination with acontainer and means for fastening the same to a railhead; of adetonator, a smoke-producing substance, and

the d an inflammable powder producing a pungent odor on ignition.

i. A railway track torpedo consisting of he combination with a containerand means for fastening the same to a rail head, of a detonator, asmoke-producing substance, a flash-light powder and an inflammablepowder producing pungent odor on ignition.

5. A. railway track torpedo consisting of metal carrier, means forsecuring the fearrier to the rail head, a container having relativelyshort folded under ends and containing a detona-tor and a diminutivefastening securing each end ofthefcontainer to the renective ends of thecarrier. I y I 6.

I I I I 7. A railway track torpedoconsisting of a metal carrier, means for securing thecarrier to the railhead, a container containing detonator the ends of saidcontainer beingfolded back upon'themselves and a diminutive fastening securing eachfolded end tothe respective ends of the carrier. I I I I I 8. A railwaytrack torpedo consisting .of a metal carrier, means for securing thecarrier to the rail head, a container containing a detonator the ends ofsa'id containerbeing folded back upon themselves, and a'rivet securingeach folded end to the respective ends of the carrier.

9. A railway track torpedo consisting of a metal carrier, spring clipsformedintewith the carrier for securing'the latter to a rail head,a'container containing a detonator, the ends of said container beingfolded back upon themselves, and arivet securing each folded end to therespective ends of the carrier.
